To all 'ui/lima 'it muy 1z0/Mom.'

lierit known that l, llli'neiaiw N. limoni', a citizen o't the United titatee, residing;` at New York, in the county and State of York, hare `iiwented certain new and use 4tui lhnprcweinente in {'iihoele'ibeorbere ilior lifehiolee, and l do hereby declare the iollowing; to be a full, Clear, and exact description of the invention, auch will enable others Skilled in the art to which it appertains to make and use the saine.

lrlljyiipreeent invention relates to anilimproved and novel instruction for use upon aeroplanee, automobiles and, indeed, vehicles oit all kinde, whereby ehoelre and vibrations `due to trariel over rough surfaces are absorbed or dissipated. in ite application to aeroplanes, ,my improvement euccees'liully relieves the aviator itrom the shock incident to landing, or at least greatly leesens its eil'ect.

lt ie a valuable characteristic ot my present invention that it serves to resist both the primary upward blows or thruete due to roupjh roads and the secondary ahoclr due to rebound and exerted 'in the opposite di reotion. lliurtherinore, l aoeon'iplieh thieI by the use ot a single pneumatie eueliion with resilient walls arranged to yield horizontally, or at right angles to the d irection oit impact. l

Single pneu in atie euehion which is arranged to re et the pressure o'li two paire oi compression platee fixed respectively to the vehicle body on the. one hand and to the truck, chaeeie, aide or other lower nii-amber on the other hand. l'llbese compression platee areI alternately ari past each other ae the body oi? the Vehicle swings up and down withrel-ation to 'the lower or wheel Carrymember.

with auxiliary mo 'able parte already familiar in the arto'i vehicle construction, endl have therefore not limited myself in this reirai-d to any particular location ot my Cushion, and yhall describe and claim it in connection with a body member and a` loweiz member broadly so desteribiul.

In liig. l the body member is indicated at l0 and may be or any eonrenient oonetruetion, while any suitable lower mein ber is indicated at ll. The shoeleabsorb ing' cushion 1Q is brought into play between theSe members preferably by the 'following means. l

,Fixed to the lower member .ll is an upwardly extending tube within which plays a sliding' spindlell-,preiierablyalso tubular, which is fixed to the body member lO. Four compression platee` l5 are [ii-Inl)` lined to the tube 13 near its upper end and are arranged to radiate symmetrically y'tliere'lfrom,' while directly below these are tour similar platee 1G (two oi? which appear in Figi'. l) whih are fixed to the tube lil nearer its lower ond. The outer endelo'l the lower plates lo are provided with lega li" which unite them with the lower member and serveA Agreatly to Strengthen them. l prefer also to unite 'the upper plateeI li with the plateel i6 at the outer ende oit both by means et pinel '1S ttor purpoees oiC greater etrenpgth.

The Spaces between the upper radiating' platee l5 are occupied by iour similar platee 19 which lie normali;v in the same plane with the platee Theec platee are fixed 1li by means ot ribs 2O passing' through 'liour slots :El in the tube 13. I Normally in the Same plane `with the lower plates lll and oeeupying' the epaeee be tween them directly under the platee lil are `iour radiating' eompreseion plates-22; and theee are also united to the spindle llby ribs 23 paeeing through the slots 21. `For purpoeel olf increaeed Strength l prefer to unite the upper plates 19 to the lower plates 2Q by pins 21.1-, ae shown in Fig. l.

Between the upper serieel of relatively movable plates l5, 3,9, andthe lower series 1G. 22, li insert a l`atout inflatable pneumatic cushion 1Q, prefer bly of the Construction ebow/n in Figi'. 3, eo made in order to permit its ready insertion between the platee when deflated. "lite" euch insertion it is inflated br means oit the ueual ralifed tube improved device -re the vehicle body si o tends to sway up Iand down n1 response to the rapidly repeated shocks of travei, the pair of compression plates 19 and 22, which are fixed to the spindle 14 and through it to the vehicle body, act to squeeze the cushion 12, first against the lower plates 16, fixed to the tube 13, and the lower member 11; and then7 on the rebound, to compress it against the upper plates 15, also fixed to the tube 13.

It will thus beseen that by my invention, a single cushion is made to take up, absorb or suppress vibratory shocks in both directions. l

It 'is clear that the principle oi' my in- Ivention may be embodied in other and modified forms or constructions.

instead of eight plate-sections in each plane I may use any convenient number. In Fig. a is shown a structure in which the outer tube 13 carries only two upper plates 151L (corresponding, ofcourse, to similar lower plates) and wherein the spindle 1a carries only two4 plates 19a (with similar lower plates, not shown).

In Fig. 5 ,there is shown only one upper plate 15"., fixed to the tube 13 and one upper plate 19", fixed to the spindle 11i.

y My shock absorbing unit may be applied to vehicles in a variety of ways, but I prefer to provide a separateunit in association with each wheel of the vehicle, as shown in Figs.

6 and 7.

In Fig. 6, the body of an aeroplane is shown at 26, andv one of the two usual wheels is shown at 27. Here there is provided a separate unit of the character above described near each end of the axle 28, and I have indicated one of these units as a whoh In Fig. 7, the body of' an automobile is shown generally at 30 and a separate shockabsorbing unit 3l is provided -for each wheel 32 of the vehicle. In the modification shew 'n .in Fig. 7, the lower member is the spring 33 and the` upper member is, in each case, a bar 34.

The advantage of supplying a separate shock-absorbing unit at or near each wheel is found in the fact that a perfect equaliza- Jtion of action is assured, and each when? i@ For instance,

' claim 8 free to respond to the. particular incipralitie.` i

which it meets, without respect to those al' ieeting other wheels.

,Vhat I claim is :w-

l.. In combination with the, body member and the lower member ol' a vehicle, a shoflv absorbing unit comprising a nele, pneumatic cushion with resilient walls i cb to es pand in every horizontal direction, and means attached to said body member and lower member, respectively. adapted io cxert pressure upon said cushion from above and below alternately.

Apparatus oi the character set forlli generally in claim 1 herco'l', wherein ille cushion is substantially of? toric form, and is free to expand horizontally both wihin and withoutthe torio circle.

3. Apparatus of the character serv lorfh generally in claim l, hereof, wherein the lower member carri a tubular element having a longitudinal slot while, the body mene ber carries a spindle playingl in said tubular element, and wherein a fixed on said tubular mem er and a pair ol: plates is fastened to said spindle by means of ribs passing through said slot.

el. In apparatus of the general chai-artnr set forth, a. tube having radiating` plates .l

fixed `thereon and provided with slots, a spindle playing in said tube, and radiating pla-tes occupying the spaces between said first named plates and. fixed lo said spindle by means passing through said slots.

Apparatus of the. character set l'orlh in hereof?, wherein the cushion is in the form or" an interrupted torus wherein.y the, same may be easily introduced into place between the pressure plates while undistcndcal.

6. In combination with the body member Eand the lower member of i vehicle, a shock absorbing unit comprising a single horizon.- tally disteudible pneumatic cushion, pressure plates on opposite sides of the cushion connected with the lower member, a second connected set of pressure plates on opposite sides of the cushion, and means for conveying the weight of the body member oiz the vehicle to the upper plates of said second setz.

In testimony whereof I afiii; my signature.
